BREAKING: Fukushima Daiichi plant has lost power

13. If it's just the fuel pools they will begin to heat.

That increases the rate of loss of water from the pools via evaporation. If the water level drops too much, we get back to a point where the spent fuel overheats, and the zircalloy cladding can burn, offgas hydrogen, fires etc.

Should take a while, more than a day to see the pools drop though, and the problem can be temporarily stopgapped by simple smaller generators, and fire pumps to spray in water.

Doesn't sound like the reactors have lost cooling. They probably can't go re-critical, but overheating could lead to increased degradation of the containment, and complicate cleanup.
